waiver of certain conditions, including among other things the receipt of
applicable regulatory approvals and the expiration of the statutory waiting
period under the Hart-Scott-Rodino Antitrust Improvements Act. In addition, the
agreement of TPG FirstWorld I LLC to purchase (and of the Company to sell) any
portion of the New Shares pursuant to the Company Purchase Agreement is subject
to the condition that such purchase, individually, or taken together with all
other persons or entities acting as a group with TPG FirstWorld I LLC within the
meaning of Section 13(d)(3) and Section 14(d)(2) of the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), (collectively, the "Group") would not
cause the Group to become the Beneficial Owner (as such term is defined in the
Company's Indenture dated April 13, 1998 (the "Indenture")) of more than 35% of
Voting Stock (as such term is defined in the Indenture) of the Company.

     Warrant Amendment. In connection with the Enron Purchase Agreement, the
Buyers and the Company entered into a Warrant Amendment, dated as of February

purchase of the Securities under the Enron Purchase Agreement, the December
Warrants shall be issued in two separate instruments, exercisable for 4,625,000
shares and 375,000 shares of Series B Common Stock, respectively. Pursuant to
the Warrant Amendment, December Warrants exercisable for 375,000 shares of
Series B Common Stock were amended such that they would not be exercisable to
the extent (but only to the extent) that such exercisability would cause the
holder of such Warrants, individually, or taken together with all other all
persons or entities acting as a group with such holder within the meaning of
Section 13(d)(3) and Section 14(d)(2) of the Exchange Act to be or become the
Beneficial Owner (as such term is defined in the Indenture) of more than 35% of
the total Voting Stock (as such term is defined in the Indenture) of the
Company. The Warrant Amendment also provides that, notwithstanding the
foregoing, such December Warrants become fully exercisable upon the earliest to
occur of (i) the 61st day following the closing of the Company's IPO, (ii)
February 15, 2001, (iii) any Change of Control (as such term is defined in the
Indenture) and (iv) any amendment to or restatement of the Company's Bylaws or
Certificate of Incorporation without the consent of Buyers or their transferees
holding a majority of the Warrants (subject to certain exceptions).

     Investor Rights Agreement. ENA and the Company (as well as certain other
holders of the Company's securities) are party to an Amended and Restated
Investor Rights Agreement dated as of April 13, 1998 (as subsequently amended,
the "Investor Rights Agreement"), to which the Buyers and TPG FirstWorld I LLC
will become party upon the consummation of the transactions contemplated by each
of the Enron Purchase Agreement and the Company Purchase Agreement,
respectively. The Investor Rights Agreement provides for certain transfer
restrictions, demand, piggyback and Form S-3 registration rights and rights of
first refusal. TPG FirstWorld I LLC will become a party to the Investor Rights
Agreement only with respect to the demand, piggyback and Form S-3 registration
rights provided for therein. In connection with the Enron Purchase Agreement,
the Buyers, the Company, ENA and certain other parties to the Investor Rights
Agreement entered into a letter agreement, dated February 10, 2000 (the
"Investor Rights Letter Agreement"), in order to assign certain rights of ENA
under the Investor Rights Agreement to the Buyers.

10.  INDEMNIFICATION

     The Sellers and Buyer each make the following covenants that are applicable
to them, respectively:

     10.1 Indemnification by the Sellers. Each Seller covenants and agrees that
it shall indemnify, defend, protect and hold harmless the Buyers and their
respective affiliates, their respective present and former directors, officers,
stockholders, employees and agents and their respective heirs, executors,
personal representatives, administrators, successors and assigns (the "Buyer
Indemnified Persons") at all times from and after the date of this Agreement
until the Expiration Date from and against all claims, damages (including
consequential, punitive or exemplary), actions, suits, proceedings, demands,
assessments, adjustments, costs and expenses (including specifically, but
without limitation, reasonable attorneys' fees and consulting fees) incurred by
or asserted against any Buyer Indemnified Persons as a result of or arising from
directly or indirectly: (a) any breach of the representations and warranties of
the Sellers set forth herein; or (b) any breach of any agreement on the part of
the Sellers under this Agreement.

     10.2 Indemnification by the Buyers. Each Buyer covenants and agrees that it
shall indemnify, defend, protect and hold harmless the Sellers and their
respective affiliates, their respective present and former directors, officers,
stockholders, employees and agents and their respective heirs, executors,
personal representatives, administrators, successors and assigns (the "Seller
Indemnified Persons") at all times from and after the date of this Agreement
until the Expiration Date from and against all claims, damages (including
consequential, punitive or exemplary), actions, suits, proceedings, demands,
assessments, adjustments, costs and expenses (including specifically, but
without limitation, reasonable attorneys' fees and consulting fees) incurred by
the Seller Indemnified Persons as a result of or arising from directly or
indirectly (a) any breach of the representations and warranties of the Buyers
set forth herein, or (b) any breach of any agreement on the part of the Buyers
under this Agreement.

     10.3 Third Person Claims. Promptly after any party hereto (hereinafter the
"Indemnified Party") has received notice of or has knowledge of any claim by a
person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, the Indemnified Party shall, as a
condition precedent to a claim with respect thereto being made against any party
obligated to provide indemnification pursuant to Section 8.1 or 8.2 hereof
(hereinafter the "Indemnifying Party"), give the Indemnifying Party written
notice of such claim or the commencement of such action or proceeding. Such
notice shall state the nature and the basis of such claim and a reasonable
estimate of the amount thereof. The Indemnifying Party shall have the right to
defend and settle, at its own expense and by its own counsel, any such matter so
long as the Indemnifying Party pursues the same in good faith and diligently;
provided that the Indemnifying Party shall not settle any such proceeding
without the written consent of the Indemnified Party. If the Indemnifying Party
undertakes to defend or settle, it shall promptly notify the Indemnified Party
of its intention to do so, and the Indemnified Party shall cooperate with the
Indemnifying Party and its counsel in the defense thereof and in any settlement
thereof. Such cooperation shall include, but shall not be limited to, furnishing
the Indemnifying Party with any books, records or information reasonably
requested by the Indemnifying Party that are in the Indemnified Party's
possession or control. All Indemnified Parties shall use the same counsel, which
shall be the counsel selected by Indemnifying Party, provided that if counsel to
the Indemnifying Party shall have a conflict of interest that prevents counsel
for the Indemnifying Party from representing Indemnified Party, Indemnified
Party shall have the right to participate in such matter through counsel of its
own choosing and the Indemnifying Party shall reimburse the Indemnified Party
for the reasonable expenses of its counsel.

     After the Indemnifying Party has notified the Indemnified Party of its
intention to undertake to defend or settle any such asserted liability, and for
so long as the Indemnifying Party diligently pursues such defense, the
Indemnifying Party shall not be liable for any additional legal expenses
incurred by the Indemnified Party in connection with any defense or settlement
of such asserted liability, except (i) as set forth in the preceding sentence
and (ii) to the extent such participation is requested by the Indemnifying
Party, in which event the Indemnified Party shall be reimbursed by the
Indemnifying Party for reasonable additional legal expenses and out-of-pocket
expenses.

     If the Indemnifying Party desires to accept a final and complete settlement
of any such Third Person claim involving only the payment of money and the
Indemnified Party refuses to consent to such settlement, then the Indemnifying
Party's liability under this Section with respect to such Third Person claim
shall be limited to the amount so offered in settlement by said Third Person.
Upon agreement as to such settlement between said Third Person and the
Indemnifying Party, the Indemnifying Party shall, in exchange for a complete
release from the Indemnified Party, promptly pay to the Indemnified Party the
amount agreed to in such settlement and the Indemnified Party shall, from that
moment on, bear full responsibility for any additional costs of defense which it
subsequently incurs with respect to such claim and all additional costs of
settlement or judgment. If the Indemnifying Party does not undertake to defend
such matter to which the Indemnified Party is entitled to indemnification
hereunder, or fails diligently to pursue such defense, the Indemnified Party may
undertake such defense through counsel of its choice, at the cost and expense of
the Indemnifying Party, and the Indemnified Party may settle such matter, and
the Indemnifying Party shall reimburse the Indemnified Party for the settlement
and any other liabilities or expenses incurred by the Indemnified Party in
connection therewith, provided, however, that under no circumstances shall the
Indemnified Party settle any Third Person claim without the written consent of
the Indemnifying Party, which consent shall not be unreasonably withheld or
delayed. All settlements hereunder shall effect a complete release of the
Indemnified Party, unless the Indemnified Party otherwise agrees in writing.

     10.4 Limitation on Indemnification. No party to this Agreement shall be
liable under this Section 10 for an amount which exceeds the Purchase Price.

11.  GENERAL

     11.1 Cooperation / Hart-Scott Act. Each of the Sellers and the Buyers shall
deliver or cause to be delivered to the other, such additional instruments as
the other may reasonably request for the purpose of carrying out this Agreement.
Buyers and the Sellers recognize that one or more filings under the Hart-Scott
Act may be required in connection with the transaction contemplated herein. If
Buyers and the Sellers determine that filings under the Hart-Scott Act are
required, then: (i) each party agrees to cooperate and use its best efforts to
comply with the Hart-Scott Act and (ii) the parties agree to cooperate and use
their best efforts to cause all filings required under the Hart-Scott Act to be
made as promptly as reasonably possible. If filings under the Hart-Scott Act are
required, each party shall pay its own costs and expenses thereof and one-half
of the filing fee.

     11.2 Successors and Assigns. This Agreement and the rights of the parties
hereunder may not be assigned except by operation of law and, in the case of
each Buyer, to one or more of Buyers' affiliates identified on Exhibit B that
are accredited investors, and shall be binding upon and shall inure to the
benefit of the parties hereto, their permitted successors and assigns. Any
assignment of rights by a Buyer will be effected by delivery of written notice
to the Sellers, executed by the relevant Buyer and the assignee. Any assignee
shall agree in writing to become a party to this Agreement and the letter
agreement regarding assignment of rights under the Investors Rights Agreement
and to be bound by all the terms of such agreements. The assignee will
thereafter be deemed to be a "Buyer" for all purposes under this Agreement.

     11.3 Limitation of Damages. Except in the case of fraud or claims asserted
under Section 10 hereof, no party shall have any liability for, and no party may
make any claim against or sue any other party for, any punitive, consequential
or incidental damages in connection with this Agreement or the transactions
contemplated hereby, whether based on breach of contract, tort or any other
theory of liability; provided, however, damages and losses recoverable pursuant
to Section 10 shall include all punitive, consequential or incidental damages
that must be paid by a party to a third party.

     11.4 Counterparts. This Agreement may be executed simultaneously in two (2)
or more counterparts, each of which shall be deemed an original and all of which
together shall constitute but one and the same instrument. A telecopied
facsimile of an executed counterpart of this Agreement shall be sufficient to
evidence the binding agreement of each party to the terms hereof. However, each
party agrees to return to the other parties an original, duly executed
counterpart of this Agreement promptly after delivery of a telecopied facsimile
thereof.

     11.5 Brokers and Agents. Each party represents and warrants that it has
employed no broker or agent in connection with this transaction, other than
Sellers' engagement of Bear, Stearns & Co. Inc. ("Bear, Stearns"), and agrees to
indemnify the other parties hereto against all loss, cost, damages or expense
arising out of claims for fees or commission of brokers employed or alleged to
have been employed by such indemnifying party. Sellers shall be solely
responsible for payment of all fees owed to Bear, Stearns as a result of the
sale of the FirstWorld Securities.

     11.6 Notices. All notices of communication required or permitted hereunder
shall be in writing and may be given by depositing the same in United States
mail, addressed to the party to be notified, postage prepaid and registered or
certified with return receipt requested, or by delivering the same in person to
an officer or agent of such party.

the laws of the State of Texas, excluding any conflicts of law, rule or
principle that might refer same to the laws of another jurisdiction.

     11.8 Exercise of Rights and Remedies. Except as otherwise provided herein,
no delay of or omission in the exercise of any right, power or remedy accruing
to any party as a result of any breach or default by any other party under this
Agreement shall impair any such right, power or remedy, nor shall it be
construed as a waiver of or acquiescence in any such breach or default, or of
any similar breach or default occurring later; nor shall any waiver of any
single breach or default be deemed a waiver of any other breach or default
occurring before or after that waiver.

     11.9 Time. Time is of the essence with respect to this Agreement.

     11.10 Reformation and Severability. In case any provision of this Agreement
shall be invalid, illegal or unenforceable, it shall, to the extent possible, be
modified in such manner as to be valid, legal and enforceable but so as to most
nearly retain the intent of the parties, and if such modification is not
possible, such provision shall be severed from this Agreement, and in either
case the validity, legality and enforceability of the remaining provisions of
this Agreement shall not in any way be affected or impaired thereby. No
provision of this Agreement shall be interpreted or construed against any party
solely because that party or its legal representative drafted such provision.

     11.11 Remedies Cumulative. No right, remedy or election given by any term
of this Agreement shall be deemed exclusive but each shall be cumulative with
all other rights, remedies and elections available at law or in equity. The
exercise of any remedy shall not preclude the simultaneous or later exercise of
any other remedy.

     11.12 Captions. The headings of this Agreement are inserted for convenience
only, shall not constitute a part of this Agreement or be used to construe or

written consent of the Buyers and each of the Sellers. Any amendment effected in
accordance with this Section 11.13 shall be binding upon each of the parties
hereto.

this Agreement, including any question regarding its existence, validity or
termination, shall be referred to and finally resolved by binding arbitration
governed by the Federal Arbitration Act and conducted in accordance with the
American Arbitration Association Commercial Arbitration Rules which Rules are
deemed to be incorporated by reference into this clause. The number of
arbitrators shall be three, the Buyers having the right to appoint one
arbitrator and the Sellers having the right to appoint another arbitrator, which
arbitrators shall together then appoint a third neutral arbitrator within thirty
(30) days in accordance with the Rules. The third arbitrator shall be a person
who has five years or more experience in the relevant industry. The place of
arbitration shall be Houston, Texas, USA, where all hearings and meetings shall
be held. The parties hereby expressly waive any right of appeal to any court
having jurisdiction on any question of fact or law.

     11.15 Entire Agreement. This Agreement (including the schedules attached
hereto) and the documents delivered pursuant hereto constitute the entire
agreement and understanding among the Sellers and the Buyers and supersede any
prior agreement and understanding relating to the subject matter of this
Agreement.

                                WARRANT AMENDMENT


     This Warrant Amendment (this "Agreement") is entered into among FirstWorld
Communications, Inc. (the "Company"), and TPG Partners III, L.P., a Delaware
limited partnership ("TPG III"), T3 Partners, L.P., a Delaware limited
partnership ("T3") and Colony Investors IV, L.P., a Delaware limited partnership
("Colony") as of the 10th day of February 2000. TPG, T3 and Colony are referred
to collectively in this Agreement as the "Purchasers." The Purchasers and the
Company are herein referred to as the "Parties."

     WHEREAS, the Purchasers have entered into a Stock Purchase Agreement dated
February 10, 2000 with Enron North America Corp. and ECT Merchant Purchases
Corp. (the "Purchase Agreement") pursuant to which the Purchasers have agreed to
purchase (the "Purchase") certain shares of Series A Common Stock of the
Company, which will convert automatically upon the Purchase into shares of
Series B Common Stock of the Company, shares of outstanding shares of Series B
Common Stock (collectively, the "Shares"), and certain warrants to purchase
shares of Series B Common Stock of the Company (the "Warrants"). The Shares and
Warrants are referred to herein as the "Securities".

     WHEREAS, pursuant to the Indenture dated April 13, 1998 (the "Indenture"),
the Company is subject to certain obligations triggered by a Change of Control,
as such term is defined in the Indenture.

     WHEREAS, the Parties have agreed that, as a condition to the transfer of
the Securities as outlined in the Purchase Agreement, the Warrants shall be
amended to provide that the Purchasers shall not be entitled to exercise a
portion of the Warrants to the extent that the exercise thereof would give rise
to a Change of Control under the Indenture.

     NOW, THEREFORE, in consideration of the premises and the mutual agreements
contained herein and for other good and valuable consideration, the sufficiency
and receipt of which are hereby acknowledged, the Parties hereby covenant and
agree as follows:

     1.1 Issuance of Separate Warrants. Upon the closing of the Purchase of the
Securities, the December Warrants (as defined in the Purchase Agreement) shall
be issued in two separate instruments, exercisable for 4,625,000 shares and
375,000 shares of Series B Common Stock, respectively. Such Warrants shall be
identical in all respects except as set forth in Section 1.2 below.

     1.2 Amendment to Warrant to Purchase Series B Common Stock. Effective upon
the closing of the Purchase of the Securities, Section 1.1 of the December
Warrant exercisable for 375,000 shares of Series B common stock shall be amended
to insert following the last sentence of such Section 1.1:

     "Notwithstanding anything to the contrary herein, this Warrant
     shall not be exercisable to the extent (but only to the
     extent) that such exercisability would cause the holder of
     such Warrant, individually or taken together with all other
     persons or entities acting as a group with such holder within
     the meaning of Section 13(d)(3) and Section 14(d)(2) of the
     Securities Exchange Act of 1934, as amended, to be or become
     the Beneficial Owner (as such term is defined in the
     Indenture) of more than 35% of the total Voting Stock (as such
     term is defined in the Indenture) of the Company; provided
     that, notwithstanding the foregoing, this Warrant shall become
     fully exercisable upon the earlier to occur of (i) the 61st
     day following the Company's initial public offering of shares
     of the Company's Common Stock, (ii) February 15, 2001, (iii)
     any Change of Control (as such term is defined in the
     Indenture) and (iv) any amendment to or restatement of the
     Company's Bylaws or Certificate of Incorporation without the
     consent of Purchasers or their transferees holding a majority
     of the Warrants (other than an amendment to increase the
     number of shares of the Company's authorized Series B Common
     Stock to a number not to exceed 150,000,000 shares in the
     aggregate or any amendment required by applicable law)."

     1.3 Assignment. Any person to whom a Purchaser assigns any of its rights
under the Purchase Agreement shall be deemed to consent and agree to this
amendment of the Warrants.

     1.4 Other Terms; Entire Agreement. All other terms of the Warrants shall
remain in full force and effect. This Agreement sets forth all of the promises,
agreements, conditions, understandings, warranties and representations by or
among the Parties with respect to the actions contemplated hereby, and
supersedes all prior agreements, arrangements and understandings by or among the
Parties relating to such actions, whether written, oral or otherwise. There are
no promises, agreements, conditions, understandings, warranties or
representations, oral or written, express or implied, by or among the Parties
except as set forth herein, except as to the terms of the Warrant which continue
pursuant to the terms hereof.

     WHEREAS, the Investor has indicated a desire to purchase the number of
shares of the Company's Series B Common Stock ("Common Stock") obtained by
dividing $50,000,000 by 93% of the per share price paid by the public for the
Company's Common Stock in the Company's initial public offering (the "IPO").

     WHEREAS, the Company has indicated a desire to sell the number of shares of
the Company's Common Stock obtained by dividing $50,000,000 by 93% of the per

Agreement, the Company agrees to sell to the Investor and the Investor agrees to
purchase from the Company the number of shares of the Company's Common Stock
obtained by dividing $50,000,000 by 93% of the per share price paid by the
public for the Company's Common Stock in the Company's IPO (the "Stock"), having
the rights, preferences, privileges and restrictions set forth in the
Certificate of Incorporation of the Company (the "Certificate") on file with the
Delaware Secretary of State as of the Closing (as defined below).

     1.2 The Closing. The purchase and sale of the Stock shall be held at the
Company's offices immediately following the closing of the Company's IPO (the
"Closing"). At the Closing, the Company will deliver the Stock to the Investor
against payment of the purchase price therefor by check payable to the order of
the Company or by wire transfer. The per share purchase price for the Stock
shall be 93% of the per share price paid by the public for the Company's Common
Stock in the IPO.

2. Representations and Warranties of the Company. Except as set forth on the
schedule of exceptions delivered herewith, the Company hereby represents and
warrants to the Investor that:

     2.1 Organization and Good Standing. The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware and has all requisite corporate power and authority to carry on its
business as now conducted. The Company is duly qualified to transact business

     2.2 Authorization. All corporate action on the part of the Company, its
officers, directors and stockholders necessary for the authorization, execution
and delivery of this Agreement, the performance of all obligations of the
Company hereunder, and the authorization, issuance, sale and delivery of the
Stock has been taken or will be taken prior to the Closing, and this Agreement
constitutes a valid and legally binding obligation of the Company, enforceable
in accordance with its terms, except (i) as limited by applicable bankruptcy,
insolvency, reorganization, moratorium, and other laws of general application
affecting enforcement of creditors' rights generally and (ii) as limited by laws
relating to the availability of specific performance, injunctive relief, or
other equitable remedies.

     2.3 Valid Issuance of Stock. The Stock, when issued, sold and delivered in
accordance with the terms hereof for the consideration expressed herein, will be

contemplated by this Agreement are exempt from the registration requirements of
any applicable state and federal securities laws.

     2.4 Title to Property and Assets. The Company owns its property and assets
free and clear of all mortgages, liens, loans and encumbrances, except such
encumbrances and liens that arise in the ordinary course of business and do not
materially impair the Company's ownership or use of such property or assets.
With respect to the property and assets it leases, the Company is in compliance
with such leases, except to the extent such non-compliance would not materially
impair the Company's business or prospects and, to the best of its knowledge,
holds a valid leasehold interest free of any liens, claims or encumbrances. The
Company is subject to the debt covenants and other terms and conditions set
forth in the Indenture dated April 13, 1998 between the Company and the Bank of
New York as Trustee (the "Indenture").

     2.5 Compliance with Other Documents. The execution and delivery of this
Agreement, consummation of the transactions contemplated hereby, and compliance
with the terms and provisions hereof will not conflict with or result in a
breach of the terms and conditions of, or constitute a default under the
Restated Certificate or Bylaws of the Company or of any contract or agreement to
which the Company is now a party, except where such conflict, breach or default
of any such contract or agreement, either individually or in the aggregate,
would not have a material adverse effect on the Company's business, financial
condition or results of operations.

     2.6 Registration Statement. The Company's registration statement on Form
S-1, as amended, (the "Registration Statement") shall not, at the time the
Registration Statement (including any amendments or supplements thereto) is
declared effective by the Securities and Exchange Commission ("SEC"), contain
any untrue statement of a material fact or omit to state any material fact
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading.

     2.7 Capitalization. The Company's capitalization information contained in
the Registration Statement is complete and accurate as of the dates specified
therein.

     2.8 Litigation. Except as disclosed in the Company's Registration
Statement, to the best of the Company's knowledge, there are no actions,
proceedings or investigations pending against the Company, that, either in any
case or in the aggregate, would result in any material adverse change in the
business, financial condition, or results of operations of the Company.

     2.9 Intellectual Property. Except as disclosed in the Registration
Statement, the Company owns, possesses or can acquire on reasonable terms,
adequate trademarks, trade names and other rights to inventions, know-how,
patents, copyrights, confidential information and other intellectual property
(collectively, "Intellectual Property Rights") necessary to conduct the business
now operated by it, or presently employed by it, and has not received any notice
of infringement of or conflict with asserted rights of others with respect to
any intellectual property rights that, if determined adversely to the Company,
would individually or in the aggregate have a material adverse effect on the
condition (financial or other), business, properties or results of operations.

     2.10 Financial Statements. The financial statements included in the
Registration Statement present fairly the financial position of the Company as
of the dates shown and its results of operations and cash flows for the periods
shown, and, except as otherwise disclosed in the Registration Statement, such
financial statements have been prepared in conformity with the generally
accepted accounting principles in the United States applied on a consistent
basis.

     2.11 Changes. Except as disclosed in the Registration Statement, since the
date of the latest audited financial statements included in the Registration
Statement there has been no material adverse change, nor any development or
event involving a prospective material adverse change, in the condition
(financial or other), business, properties or results of operations of the
Company taken as a whole.

     2.12 Taxes. The Company has filed on a timely basis all tax returns and
reports (including information returns and reports) as required by law. These
returns and reports are true and correct in all material respects except to the
extent that a reserve has been reflected on the Company's financial statements
in accordance with generally accepted accounting principles. The Company has
paid all taxes and other assessments due, except those contested by it in good
faith and except to the extent that a reserve has been reflected on the
Company's financial statements in accordance with generally accepted accounting
principles. The provision for taxes of the Company as shown in the Company's
financial statements is adequate for taxes due or accrued as of the date
thereof.

3. Representations and Warranties of the Investor. The Investor hereby
represents and warrants that:

     3.1 Authorization. This Agreement constitutes the valid and legally binding
obligation of the Investor, enforceable in accordance with its terms, subject to
laws of general application relating to bankruptcy, insolvency and the relief of
debtors and by general principles of equity.

     3.2 Investigation. The Investor acknowledges that it has had an opportunity
to discuss the business, affairs and current prospects of the Company with the
Company's chief executive officer. The Investor further acknowledges having had
access to information about the Company that it has requested or considers
necessary for purposes of purchasing the Stock. The foregoing, however, does not
limit or modify the representations and warranties of the Company in Section 2
of this Agreement or the right of the Investors to rely thereon.

     3.2 Institutional Accredited Investor. The Investor is a large
institutional accredited investor. "Accredited Investor" has the meaning
ascribed to it in Regulation D as promulgated under the Securities Act of 1933,
as amended.

     3.4 Purchase Entirely for Own Account. This Agreement is made with the
Investor in reliance upon the Investor's representation to the Company, which by
the Investor's execution of this Agreement the Investor hereby confirms, that
the Stock will be acquired for investment for the Investor's own account, not as
a nominee or agent, and not with a view to the resale or distribution of any
part thereof, and that the Investor has no present intention of selling,
granting any participation in, or otherwise distributing the same.

     3.5 Restricted Securities. Investor understands that the Stock it is
purchasing are characterized as "restricted securities" under the federal
securities laws inasmuch as they are being acquired from the Company in a
transaction not involving a public offering and that under such laws and
applicable regulations such securities may be resold without registration under
the Act, only in certain limited circumstances. In this connection, Investor
represents that it is familiar with SEC Rule 144, as presently in effect, and
understands the resale limitations imposed thereby and by the Act.

4. Conditions to the Investor's Obligation at Closing. The obligation of the
Investor to purchase the Stock at the Closing is subject to the fulfillment to
the Investor's satisfaction on or prior to the Closing of the following
conditions:

     4.1 Representations and Warranties. The representations and warranties made
by the Company in Section 2 hereof shall be true and correct when made, and
shall be true and correct as of the Closing with the same force and effect as if
they had been made on and as of such date, subject to changes contemplated by
this Agreement. The Chief Executive Officer of the Company shall deliver at the
Closing a certificate stating that the condition specified in the preceding
sentence has been fulfilled.

     4.2 Securities Laws. The offer and sale of the Stock to the Investor
pursuant to this Agreement shall be exempt from the registration requirements of
the Securities Act of 1933, as amended (the "Act") and qualification
requirements of all applicable state securities laws.

     4.3 Authorizations. All authorizations, approvals or permits, if any, of
any governmental authority or regulatory body that are required in connection
with the lawful issuance and sale of the Stock pursuant to this Agreement shall
have been duly obtained and shall be effective on and as of the Closing.

     4.4 Initial Public Offering of Common Stock. The closing of the initial
public offering of the Company's Series B Common Stock shall have occurred.

     4.5 Condition to Close. The purchase of the Stock shall be subject to a
condition to closing as to any portion of the shares of Stock proposed to be
sold pursuant to this Agreement (and only that portion), that the purchase by
the Investor, individually, or taken together with all other all persons or
entities acting as a group within the meaning of Section 13(d)(3) and Section

until the end of the restricted period.

     (c) As used in this Agreement, the term "Transfer" shall mean any sale,

securities may be resold without registration under the Act only in certain
limited circumstances, and (ii) each certificate representing the Stock and any
other securities issued in respect of the Stock upon any stock split, stock

laws.
